Hi again!
DOC: 1907 Museum catalog of ancient Egyptian mirrors. Catalog entry.
CONTEXT: 44079. Disque de miroir. - Bronze. (pl. XIX). L'orante, ***aux formes indiquées d'un trait sûr***, dans sa robe, réduite à un simple contour, s'avance, le corps légèrement incliné vers la déesse, le sein très arrondi, la tête, forte pour le corps, comme dans la réalité, le bras gauche présentant le miroir, l'autre tournant vers Maout la paume de la main dans l'attitude de l'adoration.
ATTEMPT: The female worshiper, ***with the forms indicated by/with a sure/confident/definite line/feature***, in her robe, reduced to a simple outline, advances, her body slightly inclined towards the goddess, her breast very rounded, her head, high?/strong?/large? for the body, as in real life, her left arm presenting the mirror, her right arm held up with the palm of her hand open towards Mut in the attitude of adoration.
ISSUE: I'm having trouble with more than one part of this sentence -- will post a second query if necessary -- meanwhile, how can I convey the marked part? I asked at WordRef but I'm unsure if this advice is correct, so would really appreciate at least a second opinion: "it means the forms are, sort of, emphasized. I'd say, "with underlined forms".
Thanks in advance for any help!
